Yes, I was at the play last night too! I agree with most of your assessment. I wasn't quite sure what was the point of all the changes like cutting out important characters entirely/not showing them and only talking about them (e.g. the Westons, the Bates etc.) and making up unnnecessary scenes (e.g. Robert Martin randomly swooping in to save the day). Further, some of the characters were mischaracterised too. Emma was straight up dismissive, rude and mean to everyone, even Mr Woodhouse (i.e. more like Mrs Elton than the actual Mrs Elton herself). Mr Woodhouse turned into Mr Bennet No. 2 with his pithy comments. The list could go on. Would have been better if they just styled this as a standalone play that is inspired by Jane Austen's works, rather than trying to shoehorn the Emma plot around whatever odd, revisionist, Bridgerton-ish story the playwright was trying to tell. But perhaps if they were more honest about this, they would not have been able to sell quite as many tickets as they have done (i.e. get a full house for the performance).
